[摘要] 目的 探讨骨化性气管支气管病的临床病理特点。方法 回顾性分析1例骨化性气管支气管病患者的临床、实验室检查、影像学及病理学特征并文献复习。结果 骨化性气管支气管病临床表现无特异性，高分辨CT扫描前、侧壁可见点状高密度影，后壁(膜部) 无高密度影，气管镜表现为支气管开口处见多发结节病灶，结节病理活检示粘膜下骨化、慢性炎症细胞浸润，表面呼吸上皮鳞状上皮化生伴轻度不典型增生。结论 骨化性气管支气管病比较少见，高分辨CT具有提示意义，支气管镜下表现具有特征性，其确诊需结合病理活检。

Bronchoscopy showed multiple nodules at the opening of the bronchus. Biopsy of the nodule showed submucosal ossification, lymphocyte infiltration and squamous metaplasia of the Surface respiratory epithelium with mild atypical hyperplasia .Conclusion TO is a rare disease. High resolution CT has significant clue to the diagnosis and bronchoscopy revealed characteristics. Its diagnosis should combined with pathological biopsy.
